From: Avrahams Stern <avraham.stern@xxxxxxxxx>
Receiving a provision discovery request for an ASP service that
has auto accept set to false should result in a provision discovery
response with the status field set to "currently unavailable".
Having stale P2PS provision data, results in sending a response with
the status set to success because it is mistakenly referred to as the
follow-on provision discovery request.
Fix that by clearing stale P2PS provision data in the following cases:
1. When provision discovery is complete
2. When ASP services are flushed (in which case old ASP provisioning
is no longer valid).
